Hadith 2:3

Narrated Ibn 'Umar:

While Umar bin Al-Khattab was standing and delivering the sermon on a
Friday, one of the companions of the Prophet, who was one of the
foremost Muhajirs (emigrants) came. 'Umar said to him, "What is the
time now?" He replied, "I was busy and could not go back to my house
till I heard the Adhan. I did not perform more than the ablution."
Thereupon 'Umar said to him, "Did you perform only the ablution
although you know that Allah's Apostle (p.b.u.h) used to order us to
take a bath (on Fridays)?"
